BLOG Enhancing Asphalt Durability: The Science Behind Sealcoating Oct 24, 2024

Maintaining the durability and longevity of your asphalt surfaces is crucial for avoiding costly repairs and premature deterioration. One of the most effective ways to enhance the lifespan of your asphalt is through sealcoating. Sealcoating is a protective layer that acts as a barrier against the elements, such as UV rays, water, and chemicals, which can cause damage to the surface of your asphalt. In this blog post, we will delve into the science behind sealcoating and how it can benefit your asphalt surfaces.

The primary function of a sealcoat is to seal the porous surface of asphalt, preventing water from seeping into the underlying layers. Water is one of the biggest enemies of asphalt, as it can penetrate the surface, freeze during colder temperatures, and expand, causing cracks and potholes to form. Additionally, UV rays from the sun can degrade the asphalt binder, leading to fading, oxidation, and overall deterioration of the surface. By applying a sealcoat, you create a protective barrier that shields the asphalt from these harmful elements, ultimately extending its lifespan.

Sealcoating is typically made up of a coal tar or asphalt-based emulsion mixed with water, mineral fillers, and various additives. The emulsion contains liquid asphalt, which helps to replenish the binder that holds the aggregate together in the asphalt mix. The mineral fillers improve the texture and appearance of the sealcoat, while the additives enhance adhesion, flexibility, and overall performance of the product.

The application of a sealcoat involves a thorough cleaning and preparation of the asphalt surface before the sealant is applied. Any cracks or potholes should be filled and repaired prior to sealcoating to ensure a smooth and even application. The sealcoat is usually sprayed or squeegeed onto the surface, creating a uniform layer that adheres to the asphalt. Once applied, the sealcoat needs time to cure and properly bond with the surface, usually taking around 24-48 hours depending on the weather conditions.

In addition to protecting the asphalt from water and UV damage, sealcoating also offers aesthetic benefits. A fresh coat of sealcoat can enhance the appearance of your asphalt, giving it a deep, rich, black finish that looks brand new. This can improve the curb appeal of your property and make a positive impression on visitors or customers.

Regular maintenance and reapplication of sealcoat are essential for maximizing the benefits and longevity of your asphalt surfaces. Depending on the amount of traffic and exposure to the elements, sealcoating should be reapplied every 2-4 years to ensure optimal protection and performance.
